Iranian nationalism refers to nationalism among the people of Iran and individuals whose national identity is Iranian. Iranian nationalism consists of political and social movements and sentiments prompted by a love for Iranian culture, language and history, and a sense of pride in Iran and Iranian people. Whilst national consciousness in Iran can be traced back for centuries, nationalism has been a predominant determinant of Iranian attitudes mainly since the 20th century.

During the Pahlavi dynasty (1925–1979), Iranian nationalism experienced a resurgence due to the Pahlavi government''s bolstering of patriotic sentiment. After the Iranian revolution, there has been a resurgence of nationalism within the Islamic Republic of Iran in the wake of the Iran student protests, July 1999 and the Republic''s autocratic policies over its thirty five-year existence.
